Fruot each species, we have sequenced one or more pure accessions without interspecific admixture. Local segmental ancestry of each accession can be delineated for both admixed and hybrid genotypes, based on genome-wide orignis single-nucleotide polymorphisms Supplementary Note Ctirus.

Comparative genome analysis further identified shared haplotypes among the accessions Supplementary Notes 6, 7. In particular, we demonstrate the F1 interspecific hybrid nature of Citus lime and red rough lemon oriigns different mandarin—citron hybridsMexican lime a micrantha—citron hybrid and calamondin a kumquat—mandarin hybridand confirm, using whole-genome sequence data, the origins of grapefruit a pummelo—sweet orange hybridlemon Hydration for life sour orange—citron frkit and eremorange a sweet orange and Eremocitrus glauca also known as Citrus glauca frit.

We also verified the parentage of Cocktail grapefruit, with low-acid pummelo as the seed parent and King and Dancy mandarins as the two grandparents on the paternal side. The origin of the Ambersweet orange is similarly confirmed to be a mandarin—sweet orange hybrid with Clementine as a grandparent.

We have previously shown that sour orange cv. Seville Citrus aurantium is a pummelo—mandarin hybrid, and have analysed the more complex origin of sweet orange Citrus sinensis 2. Re-analysing sequences from ten cultivars of sweet orange 3 shows that they are all derived from the same genome by somatic mutations, and were thus not included in our study.

We identified ten progenitor citrus species Supplementary Note 4. The first two principal coordinates in the multidimensional scaling Fig. medicamandarins C. reticulata and pummelos Citrus maxima —and display lemons, limes, oranges and grapefruits as hybrids involving these three species.

The nucleotide diversity distributions Fig. Hybrid accessions sour orange, calamondin, lemon and non-Australian limes with ancestry from two or more citrus species are readily identified on the basis of their higher segmental heterozygosity 1. Other citrus accessions show bimodal distributions in heterozygosity sweet orange, grapefruits and some highly heterozygous mandarins due to interspecific admixture, a process that generally involves complex backcrosses.

Among the pure genotypes without interspecific admixture, citrons show significantly lower intraspecific diversity around 0.

The reduced heterozygosity of citrons, a mono-embryonic species, is probably due to the cleistogamy of its flowers 10a mechanism that promotes pollination and self-fertilization in unopened flower buds, which in turn reduces heterozygosity.

aPrincipal coordinate analysis of 58 citrus accessions based on pairwise nuclear genome distances and metric multidimensional scaling.

The first two axes separate the three main citrus groups citrons, pummelos and mandarins with interspecific hybrids oranges, grapefruit, lemon and limes situated at intermediate positions relative to their parental genotypes.

White dot, median; bar limits, upper and lower quartiles; whiskers, 1. The bimodal separation of intraspecies light blue and interspecies light pink genetic diversity is manifested among the admixed mandarins and across different genotypes including interspecific hybrids.

Three-letter codes are listed in parenthesis with additional descriptions in Supplementary Table 2. cChronogram of citrus speciation. Two distinct and temporally well-separated phases of species radiation are apparent, with the southeast Asian citrus radiation followed by the Australian citrus diversification.

Age calibration is based on the citrus fossil C. linczangensis 16 from the Late Miocene denoted by a filled red circle. Bayesian posterior probability is 1.

dProposed origin of citrus and ancient dispersal routes. Arrows suggest plausible migration directions of the ancestral citrus species from the centre of origin—the triangle formed by northeastern India, northern Myanmar and northwestern Yunnan.

The proposal is compatible with citrus biogeography, phylogenetic relationships, the inferred timing of diversification and the paleogeography of the region, especially the geological history of Wallacea and Japan.

The red star marks the fossil location of C. Citrus fruit images in c and d are not drawn to scale. PowerPoint slide. The identification of a set of pure citrus species provides new insights into the phylogeny of citrus, their origins, evolution and dispersal.

Citrus phylogeny is controversial 1561112in part owing to the difficulty of identifying pure or wild progenitor species, because of substantial interspecific hybridization that has resulted in several clonally propagated and cultivated accessions. Some authors assign separate binomial species designations to clonally propagated genotypes 16.

Our nuclear genome-based phylogeny, which is derived fromsingle-nucleotide polymorphisms in non-genic and non-pericentromeric genomic regions, reveals that citrus species are a monophyletic group and establishes well-defined relationships among its lineages Fig.

Notably, the nuclear genome-derived phylogeny differs in detail from the chloroplast-derived phylogeny Extended Data Fig. This is not unexpected, as chloroplast DNA is a single, non-recombining unit and is unlikely to show perfect lineage sorting during rapid radiation Supplementary Note 8.

The origin of citrus has generally been considered to be in southeast Asia 1a biodiversity hotspot 13 with a climate that has been influenced by both east and south Asian monsoons 14 Supplementary Note 9. Specific regions include the Yunnan province of southwest China 15Myanmar and northeastern India in the Himalayan foothills 1.

A fossil specimen from the late Miocene epoch of Lincang in Yunnan, Citrus linczangensis 16has traits that are characteristic of current major citrus groups, and provides definite evidence for the existence of a common Citrus ancestor within the Yunnan province approximately 8 million years ago Ma.

In southeast Asia, this marked climate alteration caused major changes in biota, including the migration of mammals 18 and rapid radiation of various plant lineages 19 Australian citrus species form a distinct clade that was proposed to be nested with citrons 12although distinct generic names Eremocitrus and Microcitrus were assigned in botanical classifications by Swingle 15.

Both molecular dating analysis 21 and our whole-genome phylogenetic analysis do not support an Australian origin for citrus Rather, citrus species spread from southeast Asia to Australasia, probably via transoceanic dispersals.

This is contemporaneous with other west-to-east angiosperm migrations from southeast Asia 2324presumably taking advantage of the elevation of Malesia and Wallacea in the late Miocene and Pliocene 2526 Supplementary Note 9.

The nuclear and chloroplast genome phylogenies indicate that there are three Australian species in our collection. One of the two Australian finger limes shows clear signs of admixture with round limes Supplementary Note 5.

The closest relative to Australian citrus is Fortunellaa species that has been reported to grow in the wild in southern China Australian citrus species are diverse, and found natively in both dry and rainforest environments in northeast Australia, depending on the species Our phylogeny shows that the progenitor citrus probably migrated across the Wallace line, a natural barrier for species dispersal from southeast Asia to Australasia, and later adapted to these diverse climates.

The results also show that the Tachibana mandarin, naturally found in Taiwan, the Ryukyu archipelago and Japan 29split from mainland Asian mandarins Fig. Tachibana, as did other flora and fauna in the region, very probably arrived in these islands from the adjacent mainland 31 during the drop in the sea level of the South China Sea and the emergence of land bridges 3233a process promoted by the expansion of ice sheets that repetitively occurred during glacial maxima Supplementary Note 9.

Although Tachibana 56 has been assigned its own species Citrus tachibanasequence analysis reveals that it has a close affinity to C. reticulata 3435 and does not support its taxonomic position as a separate species Supplementary Note 4. However, both chloroplast genome phylogeny Extended Data Fig.

This suggests that Tachibana should be designated a subspecies of C. reticulatapummelo and citron 2 Extended Data Table 1. Usingancestry-informative single-nucleotide polymorphisms derived from three species, C. medicaC. maxima and C.

The pummelos and citrons represent pure citrus species, whereas in the heterogeneous set of mandarins, the degree of pummelo introgression subdivides the group into pure type-1 and admixed type-2 and -3 mandarins.

Three-letter code as in Fig. bGenealogy of major citrus genotypes. The five progenitor species are shown at the top. Whereas type-1 mandarins are pure species, type-2 early-admixture mandarins contain a small amount of pummelo admixture that can be traced back to a common pummelo ancestor with P1 or P2 haplotypes.
